SUPER EGO A couple of years ago, Muni put out a public safety campaign that showed this gorgeous woman in giant silver headphones texting ferociously right before she stepped into the path of an oncoming train. Tagline: "Do you want Beethoven to be the last thing you hear?"

Which was a bit unintentionally hilarious because, yes, I do want Beethoven to be the last thing I hear, specifically the insanely great, otherworldly "late string quartets," which would be a fine soundtrack with which to finally divest myself from this gorgeous, all-natural, all-me, not-silicone-at-all, nope-definitely-not, personal body.

But I'll take any Beethoven at all, really — and local contemporary "laptop classical" composer Mason Bates is teaming up with the SF Symphony for a special treat: two nights of great Beethoven works paired with Bates' electronica-obsessed orchestral pieces (Symphony No. 7 and The B-Sides Jan. 8-11, and Mass in CMajor and Liquid Interface Jan. 15-18, www.sfsymphony.org).

If you're unfamiliar with Bates, he uses digital and electronic instruments to bring lush, eerie dancefloor atmospherics and a leftfield backbeat to a full symphony and chorus setting. Adding Beethoven's existential and ecstatic works to the mix might start some kind of weird fire.

AMBIVALENT

The Berlin-via-NYC favorite, a.k.a. Kevin McHugh, takes a heady, design-oriented approach to techno, reaching back into minimal to tease skeins of pulsing sonic ideas into a more visceral present. And you can dance to it. With Mossmoss, Brian Knarfield, Bob Five, and more.

HOT SINCE '82

And he is hot! Out of the current crop of tech house pretty boys, Daley Padley of Leeds is also one of the sharpest, with a thoughtful sound that isn't afraid to recall your champagne hangovers and long-lost puppy love dreams.

MR. TIES

Have you heard this Berlin bearded queer techno wonder's killer, slow-burn three-hour Boiler Room DJ set? Kind of all you need to hear. He's coming in from his beloved Homopatik club to play Honey Soundsystem's "Midi Slave" party, and it will get steamy.

CIRCUIT SLAVE

Experimental psychedelic electronic music brings all the kids to the yard for a mini-festival of sorts. Headliners Circuit Slave slice punk angst through the wiring; duo Cry gets emotive with some 4AD-influenced eeriness, Bezier's loops and arpeggios drive us back to analog days. With Redredred, PSSNGRS, and PowWow.
